.FLASHING' FOR WALLSAND CHIMNFEYS.

SPECIFICATION forming part of Letters Patent No. 423,888, dated March18, 1890.

Application filed July 15, 1889- I Serial No. 317,573, (No model) I Toall whom it may concern:

Be it known that I, JAMES WHITE, a citizen of the United States,residing at Brooklyn, Kings county, New York, have invented certain newand useful Improvements in Flashings for Walls and Chimneys; fullydescribed and represented in the following specification and theaccompanying drawings, forming a part of the same.

The object of this invention is to furnish a more effective flashing forpreventing the penetration of water into buildings through thebrick-work projecting above the roof, and the improvement is adapted forapplication to either chimneys or partition-walls extended above theroof. In many cases where the flashing outside of the chimney has beenconsidered defective and water has been found upon the outer side of thechimney below the roof, I have found that the water has entered theinterior of the chimney from the top and has penetrated through thebrick-work below the roof to the outer side of the chimneywalls. Suchpenetration of the walls by water is common'in all brick constructions,as the bricks and mortar are often very porous, and the flashing in myconstruction is therefore intended, to intercept the water that may rundown upon either side of the wall and prevent its transmission to thewall at any point below the flashing. I

The invention consists in a metallic plate extended completely throughthe brick wall and having its edges bent in a suitable manher to directthe water to the desired point. In the case of a fire-wall, or otherbrick partition, extended above the roof the edges of the flashing wouldbe bent downward upon both sides of the wall, andthe briek-work belowsuch flashing would thus be protected from the water over its entireupper surface. In the case of a chimney the entire chimneywalls would beintersected in a similar manner by a metallic plate and their uppersurtying the wall above the flashing to the wall below the same, and ina chimneyflashing,

with adjustable joints, adapted to fit chimplate. Fig. 3 is an edge viewof the same plate. Fig. 4 is a plan of an adjustable chim-' ney-plate,and Fig. 5 a section of the same on line was in Fig. 4., Fig. 6 showsthe blank for the tie-piece,with dotted lines indicating whereits endswould be bent; and Fig. 7, the tie-piece with the ends bent. Fig. 8 is asection of a fire-wall, with portion of the roof, and the flashingapplied thereto. Fig. 9 represents the blank for the flashing, withdotted lines showing where the edges would be bent; and Fig. .10 is anedgeview of'the wall-flashing with bent edges.

In Figs. 2 and 3 (I, is the chimney-plate, having aperture 12 in thecenter, in which aperture the metal would be cut, as indicated by thedotted lines o c, and bent upward to form flanges c. The corners of theplate are clipped,

and dotted lines (1', near the edges of the plate,

show where the edges would be bent into flanges lettered d in Fig. 1. InFig. 1 the chimney-walls e are shown wholly divided by such plateadjacent to the roof with the flanges o bent upward in close contactwith the inner sides of the walls, and the outeredges of the plate bentdownward to form flanges 61 against the outside of the walls e. Theintersection of the Wall by the plate wholly prevents the access ofmoisture to the wall above the roof at any point below the plate, as theoutside flange throws off the water which runs down the outer side ofthe 'chimney, and the inner flanges c intercept any water that may gainaccess to the interior of the chimney and above the chimney or theiroverturning by the wind, ties f, made of flat plates or sheet' metal,are inserted within the chimney-walls transverse to the flanges c, andare provided with bent ends g, inserted within the bricks.

above and below the plate a, thus locking the outward toward the.

portions of the chimney-wall together above and below thedividing-plate.

To prevent the displacement of the brickwork upon the flashing-plate,the latter may be roughened by corrugation, as shown. in

Fig. 5, where a chimney-flashing is repre-.

sentedwith four corner-sections locked together with movable joints, andthus adapted for expansion or adjustment to fit chimneys varyingxwit'hina certain range of size. Each corner-section is formed with aninwardlybent flange I along one of its sides, adapted to embrace theedge of the adjacent cornersection, andione side of the upturned flangepose of engaging the mortar used in laying the brick, and thus lockingthe brick wall to the plate as far as possible, Similar corrugations (orindentations of other shapes to effect the same object) maybe formed inthe solid plate shown in Fig. 2, as stated above.

It is obvious that the chimney-plate may be made in two sections insteadof four, united by flanged or slip joints in a similar manner.

By means of the downwardly-bent flange m the water that may run downinside the chimney-walls is prevented from entering the slip-jointbetween the flanges, and is deflected upon the flat portion of .theplate, where it can only escape outward.

' The outer edges of the entire adjustable plate may be bent down wardoutside the walls below the plate, iii desired, in which case thecorners of the sections could be clipped oil,-

as shown in Fig. 2, to facilitate the bending of the four corners indifferent directions.

Fig.6 shows that theties used to lock the walls of the chimney togetherabove and below the flashing-plate are formed simply of flat piecesofsheet metal, which thus offer no sensible obstruction to the channelwithin the chimney, as is plainly shown in theview in Fig.

1. Similar ties maybe used in the case ofafire-wall, although the sameare, not shown in the drawings, in which Fig. 8 shows a firewall 1),projected above the roof q and having a flashing-plate 0' extendedentirely through the wall with both its projecting edges bent downwardinto flan gcs 5'. Such flashing-plate o erates to wholly cover thebrick-work abovc t it: top of the roof andto prevent the penetrationbelow the roof of any moisture that 'may penetrate the wall at any pointwhatever above the flashing-plate. The plate itself, as shown in Figs. 9and 10, consists merelyin a long strip of sheet metal with the edgesbent in the same direction, and the flashing may be applied to the-wallby forming the strip in pieces of convenient length,

placing them ,npoh the top of the wall when it is built to a certainlevel, and bending the edges-downward after the remainder of the wallhas been built, or, the sheet metal may.

bebent' into channel form before it is applied to the wall. In a wallexceeding thelength of the'metallic strip several strips wouldbe used bylapping their ends upon one another to prevent the passage of moisturethrough the same. I

-Having thus set forth my invention, what I claim herein is l 1 j 1.The-combination, with a brick wall, of a flashing-plate extendedentirely through the same, and'havingits opposite edges projectedoutside the wall and suitably bent to prevent the penetration of'moisture below the plate, substantially as herein set forth.

. 2. The combination, with the walls of a chimney, of a flashing-plateentirely. inter-' secting the walls, and having its inner edges bentupwardly within the chimney, as and for the piirposeset. forth. I

3.- The combination, with the walls of a chimney, of a flashing-plateentirely intersecting the: walls; and having its inner edges -bentupwardly within the chimney and its outer edges bent downwardly "outsidethe same, asand for'the purpose set forth.

4. An adjustable flashing-plate for chim neys, consistingin severalsections united by slip-joints and adapted to wholly intersect the.chimney-walls,as nd forthe purpose set forth. I

5'. An adjustable flashinge'plate for, chim neys, formed in severalsections adapted to wholly intersect the chimney-walls, the severalsections being'united by slip-joints and each section having an upturnedflange upon its inner edge to fit inside sucli walls, as and for thepurpose set 'forth.

6; The adjustable flashing-plate for chimneys, consisting in the 'fourcorner-sections united by slip-joints and having each the flange c bentupwardly upon its inner edge,

and the junction of the said flanges a being provided with thedownwardly-bent edges m,

adaptedto keep the water out of the slip joint between the flanges, asand for the pur- I pose set forth.

7 The combination,with a brick wall, of a flashing-plate extendedthrough the same and provided with indentations, (as corrugations,)

as described, as and for the purpose set forth.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
